This will be my first drbd setup so far here is what i have what i need to know is were does the meta data go??
2 Ubuntu 6.0.6.2 LTS servers each running dbbd built from source code. These machines are on separate networks.
Server one is older and has most things installed on raid 1 without LVM. However i have added a 20GB hard disk and set LVM and mounted a ext3 /drbd partion on it. Being a separate hard disk i am thinking this will have to be external metadata but not really clear on where and how much meta
root at mx1:/drdb# mount
/dev/md2 on / type ext3 (rw,grpquota,usrquota)
proc on /proc type proc (rw)
/sys on /sys type sysfs (rw)
varrun on /var/run type tmpfs (rw)
varlock on /var/lock type tmpfs (rw)
procbususb on /proc/bus/usb type usbfs (rw)
udev on /dev type tmpfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
devshm on /dev/shm type tmpfs (rw)
/dev/md0 on /boot type ext3 (rw)
/dev/mapper/vg-drdb on /drdb type ext3 (rw)
Server two has everything on raid 1 / and /boot are old style partitions in case something goes wrong. However i have a nice big LVM device setup on this machine it has /usr /var /opt /home and most importantly /drbd partitions on it. This is all on the same drive so i am guessing it will be internal meta data.

/dev/mapper/vg-opt on /opt type ext3 (rw)
/dev/mapper/vg-home on /home type ext3 (rw)
/dev/mapper/vg-drbd on /drbd type ext3 (rw)
This is what i have in /etc/drbd.conf on both machines of course so far i am very unclear as to what should be disk and device should i be using mapper entries like found in the mount command?
global {
usage-count yes;

device /dev/drbd1test;
disk /dev/vg/drbd;
address 68.144.188.169:7789;

}
}
WOW how did this get so complex just looking for some help here do not want to overwrite my whole harddisk or anything to crazy.
